Logistic regression (LR), discriminant analysis (DA), and neural networks (NN) were used to predict ordered and disordered regions in proteins. Training data were from a set of non-redundant X-ray crystal structures, with the data being partitioned into N-terminal, C-terminal and internal (I) regions. The DA and LR methods gave almost identical 5-cross(More)
In this paper, we proposed a low power 1-bit full adder (FA) with 10-transistors and this is used in the design ALU. Various 16-bit ALUs are designed and compared. By using low power 1-bit full adder in the implementation of ALU, the power and area are greatly reduced to more than 70% compared to conventional design and 30% compared to transmission gates.(More)
The correlation between various amino acid residues (either same or different), along the polypeptide chain have been studied using a large data base. A table of preference values for pairs having strong correlations has been constructed, which can be used to study any sequence and by calculating the weight of these sequences based on these preference(More)
We present here the results obtained by applying several different methods to quantitatively measure regularities in protein sequences based on pair-preferences. We have studied the distribution of amino acid residues, singly as well as in pairs in a large data base and have attempted this task. We confirmed the existence of well-defined pair-preferences in(More)
The analysis of primary sequences from a protein sequence data base suggests that the sequences can be considered as examples of constrained random fractals. Fractal dimensions of the positional distributions of the 20 residues along the chain have been calculated. These fractal dimensions can be used as indices of intrinsic preferences of various residues.
Autocorrelation and spectrum analyses of amino acid residues along protein chains in a large data base has been performed. Results reveal the presence of general long range correlations. Similar analyses of simulated (random) peptides do not exhibit any such long range correlations. Based on the results of nur analysis, an attempt has been made to model the(More)
Today's submicron VLSI technology has been emerged as integration of many VLSI ICs into a single Si Chip called System-on-Chip (SoC). The SoC architecture normally contains multiple processors along with either separate or centralized memory blocks as its core elements as well as many noncore elements, e.g., Cache/DRAM controllers, I/O Controllers. Due to(More)
A large protein sequence database with over 31,000 sequences and 10 million residues has been analysed. The pair probabilities have been converted to entropies using Boltzmann’s law of statistical thermodynamics. A scoring weight corresponding to “mixing entropy” of the amino acid pairs has been developed from which the entropies of the protein sequences(More)
In the context of a Doubly Fed Induction Generator (DFIG) connected to the utility grid under unbalanced voltage conditions, the controller design needs to ensure additional challenges such as restricting the Total Harmonic Distortion (THD) in grid current, minimizing the pulsations in generated power, torque, dc link voltage etc. apart from facilitating(More)
